An important goal when analyzing the causal effect of a treatment on an outcome is to understand the mechanisms through which the treatment causally works. We define a causal mechanism effect of a treatment and the causal effect net of that mechanism using the potential outcomes framework. These...

In this paper, we estimate the effect of workfare policy on crime by exploiting two exogenous welfare policy changes in Denmark. Our results show a strong decline in the crime rate among treated unemployment uninsured men relative to untreated uninsured and unemployment insured men, and part of...

Using Difference-in-Differences estimation and data from the European Community Household Panel, this paper suggests that the fixed exchange-rate policy adopted by Italy in the 1997-2000 period has reduced the real hourly wage growth of Italian full-time workers with permanent contracts, on...

Theory and evidence point towards particularly positive effects of high-quality child care for disadvantaged children. At the same time, disadvantaged families often sort out of existing programs. To counter differences in learning outcomes between children from different socioeconomic...

Excessive alcohol consumption among young people is a major public health concern. On March 1, 2010, the German state of Baden-Württemberg banned the sale of alcoholic beverages between 10pm and 5am at off-premise outlets (e.g., gas stations, kiosks, supermarkets). We use rich monthly...

This paper examines the effect of the L'Aquila earthquake on the academic performance of the students of the local university. Following this traumatic event, not only are students likely to have developed an acute stress disorder, but they have also experienced a significant disruption in their...

This paper studies the causal effects of graduating from university with an honors degree on subsequent earnings. While a rich body of literature has focused on estimating returns to human capital, few studies have analyzed returns at the very top of the education distribution. We highlight the...

In order to study whether public pension systems displace private saving, we use the quasi-experimental variation in pension wealth created by Poland's 1999 pension reform. Using the 1997–2003 Polish Household Budget Surveys, we begin by estimating "difference-in-differences" regressions,...

This paper exploits a substantial reform of the Dutch UI law to study the effect of the entitlement period on job finding and subsequent labor market outcomes. Using detailed administrative data covering the full population we find that reducing the entitlement period increases the job finding...

Using a linked employer-employee data set on the German construction industry, we analyse the effects of the introduction of minimum wages in this sector on labour market dynamics. In doing so, we focus on accessions and separations, as well as the underlying labour market flows, at the...
